Spain's Interior Ministry announced via their Twitter account on Monday that the National Police had arrested a woman in the northeastern Spanish town of Figueres, near Girona, for "attempting to recruit people to send to fight for Daesh (Isis)".
The woman, according to police sources, was working to recruit possible jihadists to send over to combat zones currently controlled by Isis, also known as Daesh, in Syria and Iraq.
The investigation is still open and more arrests are likely to follow, according to Catalan daily, La Vanguardia.
Her arrest is linked to objects seized from a suspected Islamic State jihadist, a 21-year-old Moroccan national, whom German police detained in Stuttgart last month after he fled Spain, the ministry said.
"With this arrest, a cell that was very active in promoting the ideology of the terrorist organisation Daesh, and capturing new jihadist fighters and offering logistics support, has been neutralized," the interior ministry said.It is the latest in a string of arrests related to recruiting and working for Isis.
On Saturday Spanish police arrested an 18-year-old Moroccan woman who is accused of preparing to travel to Syria to join Isis.
Police said the young woman was also suspected of recruiting other woman to join Isis via the internet. At the time of her arrest early Saturday in the coastal town of Gandia near Valencia, she "was making the last preparations for her journey" to Syria, a police statement said.
Another another was detained on the island of Lanzarote in July.
More than 100 people from Spain are suspected of having joined jihadist fighters in Iraq and Syria, and authorities fear they may return to launch attacks.
